Problems solved by technology

[0004] At present, the commonly used rice cooling methods include air-drying, air-cooling and centralized cooling, etc. Among them, air-drying cooling has poor cooling effect and slow cooling speed, which restricts the improvement of rice processing efficiency; secondly, air-cooling centralized cooling, in cooling During the process, the wind force will quickly take away the water on the surface of the rice, which will increase the temperature difference between the surface and the inside of the rice. When the thermal stress and moisture stress of the rice are greater than the tensile strength of the rice grain itself, cracks will occur in the rice grain, resulting in an increase in the broken rice rate. This type of cooling The method is difficult to promote and use in the industry

Embodiment 1

[0026] Embodiment 1, with reference to Figure 1-5 , a rice processing cooling device, comprising a cooling device main body 3, a bracket 2 is welded below the cooling device main body 3, a feed hopper 9 is welded on the top of the cooling device main body 3, a discharge hopper 1 is welded on the bottom of the cooling device main body 3, the cooling device main body 3 The top is provided with an exhaust fan 8, which runs through the main body 3 of the cooling device and extends to the inside of the main body 3 of the cooling device. The straight center lines are symmetrical to each other, and the hot air inside the main body 3 of the cooling device can be blown out by the exhaust fan 8. A heat exchange plate 13 is arranged inside the main body 3 of the cooling device, and a cavity 12 is arranged between the heat exchange plate 13 and the main body 3 of the cooling device , the function of the heat exchange plate 13 can quickly transfer the heat energy inside the cooling device...

Embodiment 2

[0027] Embodiment 2, with reference to Figure 1-3 A water outlet pipe 7 is welded above the outer wall of the main body 3 of the cooling device, and a water inlet pipe 11 is welded below the outer wall of the main body 3 of the cooling device. 11 connected, this helical structure can make the cooling water rotate up from the bottom of the cavity 12, and finally enter the outlet pipe 7 to be discharged, and take away the heat energy transmitted to the cavity 12 through the heat exchange plate 13, maximizing The temperature inside the cooling device main body 3 is greatly increased, and the cooling rate of rice is improved.

Embodiment 3

[0028] Embodiment 3, with reference to Figure 1-4 , the inner wall of the heat exchange plate 13 is located at the free end port of the material plate 10 and is welded with a mounting plate 15, one side of the mounting plate 15 is fixed with an air cooling device 5 by bolts, and one end of the air cooling device 5 is welded with a cooling air pipe 4, cooling The air duct 4 runs through the heat exchange plate 13 and the cavity 12 and extends to the outside of the main body 3 of the cooling device. The cooling air duct 4 is welded with a heat exchange tube 17 inside the cavity 12. The mounting plate 15 is a mesh structure with a mesh diameter of Smaller than the minimum diameter of the rice, when the air cooling device 5 is in operation, the natural wind from the outside can be sucked into the inside of the cooling air duct 4, and then blown through the mounting plate 15 into the rice on the material plate 10, increasing the main body of the cooling device 3 The internal air c...

Abstract

The invention discloses a rice processing cooling device. The rice processing cooling device comprises a cooling device body, wherein a bracket is welded below the cooling device body; a feed hopper is welded to the top of the cooling device body; a discharge hopper is welded to the bottom of the cooling device body; a heat exchange plate is arranged in the cooling device body; a cavity is formedbetween the heat exchange plate and the cooling device body; a mandrel is rotatably connected to the inner wall of the heat exchange plate through a bearing; material plates are welded to the outer wall of the mandrel; the mandrel penetrates through the cooling device body; and rotation regulators are connected to the two ends of the mandrel in a sleeving mode. The rice processing cooling device is suitable for cooling rice in rice processing, the rice processing cooling device ensures the cooling speed of the rice through double heat dissipation of air cooling and water cooling, and a plurality of laminated staggered material plates are arranged in the cooling device body, the material plates can maximally limit the flow path of the rice in a fixed space, and the cooling effect of the rice is further ensured.

Description

technical field [0001] The invention belongs to the technical field of rice processing, in particular to a cooling device for rice processing. Background technique [0002] Rice is a gramineous, monocotyledonous, annual herbaceous self-pollinated plant that loves temperature and humidity. According to its growth habit, rice can be divided into rice and upland rice. Rice is usually divided into two types, namely indica rice and japonica rice. Generally, indica rice originated from Subtropical, planted in tropical and subtropical regions, japonica rice planted in temperate and cold regions, rice is divided into long-grain type, medium-grain type and short-grain type according to the length of rice grains, rice is an edible grain, commonly known in southern China as "Paddy" or "millet", shelled into rice, cooked and called rice (in northern China) or white rice (in southern China), half of the world's population eats it, mainly in Asia, southern Europe and tropical America and ...
